Description

本発明はアスコクロリン系化合物を有効成分とする免疫抑制用薬剤組成物、免疫抑制用薬剤組成物を製造におけるアスコクロリン系化合物の使用、アスコクロリン系化合物を含む免疫抑制用薬剤組成物のキット、並びに臓器移植、骨髄移植または組織移植におけるアスコクロリン系化合物を使用する免疫抑制方法に関する。   The present invention relates to an immunosuppressive pharmaceutical composition comprising an ascochlorin compound as an active ingredient, the use of an ascochlorin compound in the production of an immunosuppressive pharmaceutical composition, an immunosuppressive pharmaceutical composition kit comprising an ascochlorin compound, In addition, the present invention relates to an immunosuppressive method using an ascochlorin compound in organ transplantation, bone marrow transplantation or tissue transplantation.

免疫抑制用薬剤組成物は同種組織の移植による免疫拒絶反応を抑制するほか、アレルギー疾患の治療にも使用される薬剤である。免疫抑制用薬剤組成物としては、6−メルカプトプリンとその誘導体、葉酸拮抗剤、アルキル化剤、ステロイドなどがある。免疫抑制用薬剤組成物は抗体産生の抑制のほかその作用機作は複雑であるとされている。
現在の臓器移植、骨髄移植、組織移植においてシクロスポリンA(cyclosporin A;以下、「CsA」と略す)およびFK506は、欠くことのできない臨床医薬となっている。
The drug composition for immunosuppression is a drug used for treating allergic diseases in addition to suppressing immune rejection by transplantation of allogeneic tissues. Examples of the immunosuppressive pharmaceutical composition include 6-mercaptopurine and derivatives thereof, folic acid antagonists, alkylating agents, and steroids. The immunosuppressive pharmaceutical composition is said to have a complicated mechanism of action in addition to suppression of antibody production.
In current organ transplantation, bone marrow transplantation, and tissue transplantation, cyclosporin A (hereinafter abbreviated as “CsA”) and FK506 are indispensable clinical medicines.

しかしながら、CsA等の従来の免疫抑制用薬剤組成物は症例によっては抵抗性を示したり、種々の重篤な副作用(皮膚障害、胃腸障害、肝障害、腎障害、口内炎、等)を惹起する等の問題点があった。   However, conventional immunosuppressive pharmaceutical compositions such as CsA show resistance in some cases and cause various serious side effects (skin disorders, gastrointestinal disorders, liver disorders, kidney disorders, stomatitis, etc.) There was a problem.

本発明は、CsAやFK506など従来の免疫抑制用薬剤組成物とは作用メカニズムが異なり、副作用の少ない免疫抑制用薬剤組成物を提供することを目的とする。   An object of the present invention is to provide a pharmaceutical composition for immunosuppression that has a different mechanism of action from conventional pharmaceutical compositions for immunosuppression such as CsA and FK506, and has few side effects.

上記目的を達成するために本発明者らは鋭意研究を重ねた結果、4−O−メチルアスコクロリン等のアスコクロリン系化合物に着目した。4−O−メチルアスコクロリン(以下、「MAC」と略す)は、不完全糸状菌Ascochyta viciae が生産するイソプレノイド系抗生物質アスコクロリン(ascochlorin)の合成誘導体で、下記式で示されるように、塩素原子を含むプレニルフェノール骨格というユニークな基本構造を持つ(非特許文献1を参照)。
これまでに、アスコクロリンの誘導体に関しては製法ならびに血糖低下作用(特許文献1及び2)、グリケイション阻害作用(特許文献3)が開示されている。更に、アスコクロリン誘導体をトリパノゾーマを病原体とするアフリカ睡眠病、家畜トリパノゾーマ病の予防薬・治療薬として使用することが提案されている(特許文献4)。
他方、MACは経口投与により脂質低下作用を示し、高脂血症治療薬としての臨床開発が進められている(非特許文献2〜5を参照)。
MACの免疫抑制効果について検討したところ、マウスアロ抗原免疫によるキラーT細胞の誘導を、従来より臓器移植に臨床的に用いられているCsAと同程度に強く抑制し、異種同系マウスの皮膚移植モデルで有意な移植片の生着延長効果を有することを見いだした。本発明者らはかかる知見に基づいて本発明を完成した。

In order to achieve the above object, the present inventors have conducted extensive research and as a result, have focused on ascochlorin compounds such as 4-O-methylascochlorin. 4-O-methylascochlorin (hereinafter abbreviated as “MAC”) is a synthetic derivative of the isoprenoid antibiotic ascochlorin produced by the incomplete filamentous fungus Ascochyta viciae. It has a unique basic structure called a prenylphenol skeleton containing atoms (see Non-Patent Document 1).
So far, regarding the derivative of ascochlorin, a production method, a blood glucose lowering action (Patent Documents 1 and 2), and a glycation inhibitory action (Patent Document 3) have been disclosed. Furthermore, it has been proposed to use an ascochlorin derivative as a preventive or therapeutic drug for African sleeping sickness and domesticated trypanosomiasis using trypanosome as a pathogen (Patent Document 4).
On the other hand, MAC exhibits a lipid lowering effect by oral administration, and clinical development as a therapeutic drug for hyperlipidemia is being promoted (see Non-Patent Documents 2 to 5).
The immunosuppressive effect of MAC was investigated. The induction of killer T cells by mouse alloantigen immunity was strongly suppressed to the same extent as CsA, which has been used clinically for organ transplantation. It was found to have a significant graft prolongation effect. The present inventors have completed the present invention based on such findings.

以下に実施例によって本発明をより詳しく説明する。しかし、本発明はこれらの実施例に何ら限定されない。   Hereinafter, the present invention will be described in more detail by way of examples. However, the present invention is not limited to these examples.

「実施例1」
MACの免疫抑制効果を検討するために、C57BL/6マウス(H−2b)にアロ抗原として肥満細胞腫P815(H−2d)を1匹あたり2×107個腹腔内投与した後、MACあるいはCsAを腹腔内に連日投与し、10日目に脾臓を摘出し、抗原として用いた細胞であるP815を標的細胞としてキラー丁細胞による特異的細胞傷害活性を、YAC−1細胞を用いてNK活性をCr release assayで測定した(表1)。
"Example 1"
In order to examine the immunosuppressive effect of MAC, C57BL / 6 mice (H-2b) were administered intraperitoneally with 2 × 10 7 mastocytoma P815 (H-2d) per mouse as an alloantigen, CsA was intraperitoneally administered daily, and the spleen was removed on the 10th day. Specific cytotoxic activity by killer cells using P815, which is a cell used as an antigen, as target cells, and NK activity using YAC-1 cells Was measured by Cr release assay (Table 1).

その結果、MACは50mg/kgから12.5mg/kgの投与量においてアロ抗原免疫によりて亢進した特異的キラーT細胞による細胞傷害活性を60mg/kgのCsAに匹敵する強さで抑制した。この時、非特異的細胞傷害活性を同系マウス由来の胸腺腫細胞EL−4を標的として測定したが、細胞傷害活性は全く認められなかった。このことは、この実験系ではアロ抗原によって誘導された特異的キラーT細胞活性を特異的に検出していることを示している。また同時に脾臓のNK活性に対する影響をYAC−1細胞を用いて検討した。NK活性もアロ抗原免疫により有意に上昇してくるが、MACはこの細胞傷害活性を25−50mg/kgの投与量において有意に抑制し、この効果はCsAの抑制効果を上回るものであった。
そこで次にマウス異種同系皮膚を用いた皮膚移植実験によりその免疫抑制効果を検討した。Balb/cマウス(H−2d)の左側腹部にB6マウス(H−2b)の尾部皮膚を移植し、MACあるいはCsAを移植の翌日から腹腔内に連日投与し、移植片の生着日数を測定した(表2)。
As a result, MAC suppressed the cytotoxic activity of specific killer T cells enhanced by alloantigen immunity at a dose of 50 mg / kg to 12.5 mg / kg with a strength comparable to CsA of 60 mg / kg. At this time, non-specific cytotoxic activity was measured targeting thymoma cell EL-4 derived from syngeneic mice, but no cytotoxic activity was observed. This indicates that the specific killer T cell activity induced by alloantigen is specifically detected in this experimental system. At the same time, the effect of spleen on NK activity was examined using YAC-1 cells. NK activity also increased significantly due to alloantigen immunity, but MAC significantly suppressed this cytotoxic activity at a dose of 25-50 mg / kg, and this effect exceeded that of CsA.
Then, the immunosuppressive effect was examined by skin transplantation experiment using mouse heterogeneous skin. The tail skin of a B6 mouse (H-2 b ) is transplanted into the left flank of a Balb / c mouse (H-2 d ), and MAC or CsA is intraperitoneally administered daily from the day after transplantation. Were measured (Table 2).

この系における拒絶反応は極めて強力であり、無処理群では移植した皮膚は7−8日で完全に脱落する。この時MACを投与すると、CsAの抑制効果には劣るものの、50mg/kgの投与量により有意に移植片の生着の延長効果が認められた。この時のキラーT細胞の誘導に対する影響を検討するため、10日目に脾臓を摘出し、移植皮膚片に由来するEL−4(H−2b)を標的細胞としてキラー丁細胞による特異的細胞傷害活性を、YAC−1細胞を用いてNK活性をCr release assayで測定した(表3)。 The rejection in this system is very strong and in the untreated group, the transplanted skin is completely shed in 7-8 days. When MAC was administered at this time, although the inhibitory effect of CsA was inferior, the effect of prolonging graft survival was significantly observed at a dose of 50 mg / kg. In order to examine the effect on the induction of killer T cells at this time, the spleen was removed on the 10th day, and specific cells by killer cells using EL-4 (H-2 b ) derived from the transplanted skin fragment as target cells Injury activity was measured by Cr release assay using YAC-1 cells (Table 3).

その結果、MACは25から50mg/kgの投与量において同種異系マウス皮膚移植によって亢進した特異的キラーT細胞による細胞傷害活性を60mg/kgのCsAに匹敵する強さで有意に抑制した。非特異的細胞傷害活性は同系マウス由来のP815を標的細胞として測定したが、細胞傷害活性は殆ど認められなかった。YAC−1細胞を用いて検討した脾臓のNK活性は同種異系マウス皮膚移植によりわずかに上昇してくるが、MACはこの細胞傷害活性を25−50mg/kgの投与量において有意に抑制した。
以上の結果はMACがCsAに匹敵する免疫抑制用薬剤組成物として臨床的に用いることが可能であることを示している。CsAおよび、その作用点を一にするFK506は現在の臓器移植、骨髄移植において欠くことのできない臨床医薬となっている。MACはこれらの薬剤と同様に臓器移植や骨髄移植における免疫抑制用薬剤組成物として用いること可能である。またMACの作用点はこれらの薬剤とは異なり、アポトーシスの誘導にあると考えられるため、これらの薬剤と併用することにより、より高い免疫抑制作用を引き出すことや、これらの薬剤に対して抵抗性を示す症例に対して有効性を示す可能性が期待できる。さらに、FK506が臓器移植における免疫抑制用薬剤組成物としてのみならず、アトピー性皮膚炎のような疾患に応用されているがごとく、MACにおいても他のT細胞の関与する免疫系の異常亢進を原因とする疾患にも適用できると考えられる。このような疾患とは、アトピー性皮膚炎や喘息に代表される外来抗原に対する過敏症やリューマチや膠原病、I型糖尿病に代表される自己抗原に対する自己免疫疾患である。以上のように、MACを幅広い適用範囲を持つ免疫抑制用薬剤組成物として臨床的に応用できる新規化合物として応用することが本発明の内容となる。
As a result, the MAC significantly suppressed the cytotoxic activity by specific killer T cells enhanced by allogeneic mouse skin transplantation at a dose of 25 to 50 mg / kg with a strength comparable to CsA of 60 mg / kg. Nonspecific cytotoxic activity was measured using P815 derived from syngeneic mice as a target cell, but almost no cytotoxic activity was observed. The spleen NK activity examined using YAC-1 cells slightly increased by allogeneic mouse skin transplantation, but MAC significantly suppressed this cytotoxic activity at doses of 25-50 mg / kg.
The above results indicate that MAC can be clinically used as a pharmaceutical composition for immunosuppression comparable to CsA. CsA and FK506 having the same action point are indispensable clinical medicines in current organ transplantation and bone marrow transplantation. Like these drugs, MAC can be used as a pharmaceutical composition for immunosuppression in organ transplantation and bone marrow transplantation. In addition, the action point of MAC is different from these drugs and is considered to be in the induction of apoptosis. Therefore, when used together with these drugs, higher immunosuppressive action can be obtained and resistance to these drugs can be obtained. The possibility of showing effectiveness for the case showing can be expected. Furthermore, as FK506 is applied not only as a pharmaceutical composition for immunosuppression in organ transplantation but also in diseases such as atopic dermatitis, MAC also promotes abnormal enhancement of the immune system involving other T cells. It is thought that it can be applied to the disease causing it. Such diseases are hypersensitivity to foreign antigens typified by atopic dermatitis and asthma, and autoimmune diseases against self antigens typified by rheumatism, collagen disease, and type I diabetes. As described above, it is the content of the present invention to apply MAC as a novel compound that can be clinically applied as a pharmaceutical composition for immunosuppression with a wide range of applications.

本発明のアスコクロリン系化合物は、CsAやFK506のような従来の免疫抑制剤と作用点を異にするため、これらの薬剤と併用することによってより高い免疫抑制作用を引き出すための、あるいは、これらの薬剤に対して抵抗性を示す症例に適用するための新たな免疫抑制剤としての用途が期待できる。

The ascochlorin compound of the present invention has a different point of action from conventional immunosuppressive agents such as CsA and FK506, so that it can be used in combination with these agents to bring out a higher immunosuppressive effect, or these It can be expected to be used as a new immunosuppressive agent to be applied to cases showing resistance to other drugs.
